Now you know: Summer heat

Forecasters at the National Weather Service at Memphis expect the temperature to climb into the upper 80s today with a heat index of 90 to 93 degrees.

• With the heat comes risks, and each year people die from preventable heat-related causes. A 47-year-old North Memphis woman was found dead last week in her apartment, which was not air-conditioned. Health Department officials said heat was a contributing factor.

• There were 35 heat-related deaths in Tennessee from 2004 through 2009. Five deaths were recorded in Arkansas and seven in Mississippi during the same time period.

• About 45 percent of those deaths occurred indoors, about 35 percent took place outdoors and about 15 percent were in vehicles.

• The highest number of deaths in any one of those years was 16 in Tennessee in 2007.
